The country that invented the Olympic Games is Greece. The ancient Olympic Games began in Olympia in 776 BC and were held in honor of Zeus. These games featured various athletic competitions, including running, wrestling, and chariot racing, attracting participants from different Greek city-states. The games not only celebrated physical prowess but also served religious and cultural purposes. They continued until 393 AD when Emperor Theodosius I abolished them, viewing them as pagan festivals. The modern Olympic Games were revived in 1896 by Pierre de Coubertin, inspired by the ancient tradition, and they continue to foster international sportsmanship and unity today.
